What are some things water will adhere to? and What are some things water will not adhere to?

Answers

Answer:

1. Water has an amazing ability to adhere (stick) to itself and to other substances. Hydrogen bonds form when hydrogen atoms covalently bonded to nitrogen (N), oxygen (O), or fluorine (F) in the form of covalent compounds such as ammonia (NH3), water (H2O) and hydrogen fluoride gas (HF).

2. In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.

A polar bear has thick, white fur that camouflages it when it sits on snow. Which type of adaptation is this modification?

For example: white fox hides in the snow from the predators

Camouflage is a clear example of Physical or Structural adaptations.

-Body shape, color and body patterns are the adaptations that assists both predators and prey to camouflage

-As in the example mentioned, the polar bear with its white fur hides in the snow and waits for the right time to attack its prey without being seen

Answers

Answer:

Co2 is released during both lactic acid and alcoholic fermentation reactions.

Water is produced as a result of fermentation reactions.

Explanation:

I took the test and the person above me is correct

Respiration taking place in presence and absence of oxygen has different end products. Aerobic respiration has the end products as carbon dioxide and water, alcohol is the end product of anaerobic respiration.

What is respiration ?

It is the process in which the complex substituents are broken into simpler products in the presence of oxygen and absence of oxygen in  order to produce energy.

In the aerobic respiration processes like glycolysis takes place where the glucose breaks down into 4  molecules of ATP with the consumption of 2 ATP molecules. 1 glyceraldehyde molecule is produced from the glucose that is 2 glyceraldehyde molecules are produced. Total of 4 ATP are produced.

Alcoholic fermentation is the anaerobic respiration that says the anaerobic respiration where the glucose is broken down into alcohol and water. In the anaerobic respiration, excess of alcohol gets broken  down into lactate.

What happens when the chemical bond that holds the third phosphate is broken?

Answers

The chemical bond between the second and third phosphate groups is a high energy bond. When that bond is broken, energy is released, producing ADP (adenosine diphosphate).

The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

What is phosphate bond?

The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.

This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.

Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.

Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Look at the diagram. Name organ 1.

Answers

Answer:

Organ 1: Stomach

Explanation:

The stomach holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a useable form. The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver. The large intestines are to absorb water and salts from the material that has not been digested as food and get rid of any waste products left over. By the time food mixed with digestive juices reaches your large intestine, most digestion and absorption have already taken place. The small intestines have three parts:  the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body. The small intestine is part of the digestive system.
